Zee Media BureauPeoria, Illinois: In a medical breakthrough, doctors at a hospital in Illinois implanted an artificial trachea into a two-and-half-year-old Korean toddler, Hannah Warren, born without a windpipe. The artificial windpipe made from plastic fibers and stem cells extracted from the child`s hip bone was implanted on April 9 by an international group of doctors led by Dr Paolo Macchiarini, a specialist in the field of regenerative medicine, in a nine-hour long procedure at Children`s Hospital of Illinois. Macchiarini, the director of the Advanced Center for Translational Regenerative Medicine at the Karolinska Institute in Stockholm, said the transplant crosses frontiers by eliminating the need for a human donor and a lifetime of immunosuppressant drugs.
